You won't see me online because my copy is illegal.

We've got about eighty people playing over the LAN here at school, an extremely competitive group with clans and the like. Our main focus is Counterstrike, which is played almost every day. I'm clan leader of .::Radiance::. , ranked best clan, and personally I'm third in the school. So I'm pretty good. We practice on quite a few MODs for various different reasons.
We just discovered The Specialists. No one is really that great at it, but it's so damn fast-paced and it's a much more difficult mod that CS, so after playing that a little to warm up we kick so much ass it's not even funny. That and it's fun as hell - I
love kung-fuing people up the ass.
Sven Coop, if anyone has ever played it, is one of the best mods I've seen yet, second only to The Specialists. We use it as team-building and communication practice - no one uses voicechat. Quite fun. Helps us adapt quickly to new and different situations.
I played Poke646 just for fun. Awesome mod. Kicks ass. Everyone should play it. Great custom weapons, monsters, and textures. Nice plot, too. Single player only though, unfortunately.
Deathmatch classic is plain old quake-style fun. Good stuff. 'Nuff said.
Yeah. We've also played the other more standard mods like TF, OF, Firearms a little, and HLDM. I'm not too keen on them, though. Like I said, we mainly play CS.
